Module 1 Revision
The order of these revision notes is that of the syllabus.
The notes I have written are in the order of the scheme of work we teach at St
Mary's. Therefore there will be discrepancies in the order.
The Heathcote I refer to is the First Edition.
The hyperlinks worked when I prepared these notes.
However some good sites can go off-line, which is obviously completely out of my
control.
| How to Use these Notes:
·
Read the Topic
Notes. You may also wish to look up the relevant sections in Heathcote.
·
Use the websites
suggested. The questions are generally relevant to the website.
·
Attempt
past paper questions at the end of each section.
·
At the end of
each section, sum up the key points in the form that will help you
most, e.g. Concept map, bullet points, pictures, or whatever. |
